But there's a psychological impact in the other markets that makes them bullish too I think. When people see "wow, bitfinex $1350? let's buy right now!" they buy on other exchanges with legit money and it ends up pumping the price in the rest of the market. Make no mistake, a lot of people act like this, they don't do any research.
That's definitely what happened with the MtGox highs. People were buying btc to get their money out of the exchange, but the wider world still thought MtGox was basically sound and just having a few solvable problems and pumped up to match the mtgox price.
I think it's different now. Bitcoiners have now been through so many shennanigans that they've seen it all and no longer act blindly. Everyone and their dog will know the true reason for the bitfinex highs and will be ignoring them.
